A British Columbia man was airlifted to a Calgary hospital Thursday after fending off a grizzly bear attack on a mountainside in the Rocky Mountains near the B.C.-Alberta border, according to RCMP.

Police said a father and son were tracking a bear west of Highway 43 south of Elkford, B.C., when the 36-year-old son was “attacked suddenly by an adult grizzly bear” around 3 p.m. PT.

“The man was able to defend himself with his firearm and the bear ran off,” while his father called for help, Elk Valley RCMP said in a news release Friday morning.

The man, who police said lives in nearby Sparwood, B.C., suffered several injuries, including broken bones and cuts and scrapes on his body, the release said.
